I have a 90 accord. The trans wont shift and the green S light is on. Seems as if the car is starting off in the wrong gear or is in some kind of limp mode. Any help would be appreciated.

 

That S light means a code was stored in the transmission computer.

The TCU is located under the passenger's carpet towards the firewall. Just pull back the carpet, turn the key to the II position. Count the flashes on the led of the TCU. A long flash =10 and a short flash=1.

Post the code(s) on here, and we can help figure out the specific problem.

 

I checked the codes. The TCU light stayed solid. NO blinks at all and wouldnt shut off. The ECU blinked 5 times with the last one being very short.

Ive been searching the internet and it seems that I need a new TCU. Can anyone confirm? I found a company that rebuilds them. Now how the heck do I pull this thing out? I unbolted the cover, but I cant pull it out. Theres some harnesses attached and I cant pull it back far enough to see how to get them off since they are bolted to said cover. Any other tips or tricks to get this thing out would be appreciated. I just dont want to break anything trying to get this thing off.
